My vision is to create spaces of sculptural lightness that inspire ideas, promote joy and elevate sustainable systems.
Matthias Olt works as a talented design leader and architect. His distinct use of softly swooping waves or crisp, clean lines can be found on culturally significant and sustainably designed buildings across Asia, Europe, the Middle East, and North America. Notable examples of his work include Lotte Center Hanoi, Huarun Tower, Chengdu, China, and The Net, Seattle, USA. Matthias, originally from Frankfurt, Germany, has worked in the industry for 30 years. It’s in sustainability where Matthias truly shines. Most recently, he has pitched bringing wood back into architecture in a big way. His vibrant, climate-aware designs for hybrid builds that include steel or carbon fiber wrapped with wood and cased in cement are a nod to minimalistic and forward-thinking design. In 2022, Matthias received a Fast Company Innovation by Design Award for his design of the unTower, aka Use-Neutral Tower. In 2017, Matthias received an AIA Seattle Honors Award for his innovative design of a 39-story Conceptual Mass Timber Tower in Seattle. Matthias is a registered architect and received the German architecture diploma from the University of Applied Sciences, Frankfurt, Germany, and he also holds an undergraduate degree in chemical science.
